For a given request, it take 4 s on the master and 8 s on the slave.
The query is execute via a web service. The 2 databases are on
2 distinct server. On the 2 servers, there is a jboss. the configuration
of the server is exactly the same like the configuration of the JVM
for the jboss. The servers are on the same network and communicate
with one apache. So i don't understand why the queries is slower on
the slave than on the master. The only difference is the su state of
the database. But it can be interresting to pass the slave read-write
and see if there is the same difference with the master.
